I didn't know who to ask, the other Doctors don't seem to be worried at all. Although... [One is sick, one moved out, one lost his most important person, and she doesn't really know the others.] maybe they are and I simply can't see it.

I try not to stay inside. [Because the feeling, the knowing of something... someone missing is just too palpable.]

It's easier not to think about it when you busy your mind and hands.
